SWITCH BOARD 0R MOUNTING.

Specification of Letters Patent.

Patented May 29, 1917.

Application led October 5, 1914. Serial No. 865,006.

electric switch boards or mountings adapt! ed to carry or support the elements necessary for receiving or distribution of elec- I trical circuits.

The objects yin view are to construct such an apparatnsin a simple, compact and readily available form, providing ample room and .capacity .tor attachments and connections of the variousv conductor elements, with economy of material and space.

To mount the elements on bases or boards so as to eliminate the bus bars and the conductor parts from the face thereof.

To reduce the Vamount of copper and insulating material and to so arrange the switches Aas to act cooperatively with the main bus bars and to eliminate sub bus bars between the main bus bars and the branch circuit terminals.

To arrange the lfuse devices adjacently and successively so as to be of the same polarity.

To mount the switches between panels and on 'the bus bars and to arrange the `l'use attachments on the outer sides of said panels so that a terminal pole of each of the various circuits will have a terminal pole on each of the panels.

Such an arrangement enables me to arrange the switches and fuse devices in such a manner as to utilize all the available space of the bus bars and the insulator panels and also, in such an arrangement, to arrange front plates covering all the conductor parts so that persons operating the switches will not come into contact therewith.

In a two wire distribution of a three wire l system, I preferably arrange the plus (-1-) and minus bars in the same line, and the neutral (i) bus bars parallel to the plus and minus bus bars. In such arrange ment,`and with the arrangement of the baseboards, switches and fuse devices as hereinafter described, it will be seen that there is resulting general economy in regard to material, workmanship, space and eiliciency, due to the reduction of the number of conductor-joints and the shortening of space between the bus bars andthe branch circuit terminals.

The switch board or mounting, per 8c, is compactly constructed in a simplemanner and all parts are easy of'afccessa in case of derangement.

-ln the accompanying drawings showing preferred constructions or adaptations of the inventionfd I Figure 1 is a perspective view of a complete switch board or mounting, one of the switch covering plates being removed.

Fig. 2 is a cross sectional view, indicated by the sectionline Il. Il. of Figl.

Fig. 3 is a diagram showing the relative arrangement and wiring` for the circuits.

leierring to' the drawings, the insulating' bases 2 ,and 43 of suitable insulating material, are mounted in any convenient manner and preferably connected by endmost bracglgets 4l, one at each end, whereby the board may be mounted upon any supporting frame or wall. As thus arranged, the bases 2, 3 `confront each other, extending edgewise outwardly from the wall .or other support, .or from the back surface of an inclosing cabinet, if used. p

Arranged along` the inner Vface 4of one of the insulating bases 2, arevthe bus barsB, 9, or' diiferent polarity.` as indicated by the signs and respectively; On thejinner side of the opposite base 3, opposite bus bars b5k and 9 and parallel therewith, isthe neutral bus bar 1 0, its polarity being indicated by the plus or minus sign i.

Located between the bases 2, 3, and for the purpose of connecting` the bus bars 8 and 10 are switches A, B, C, each having one of its terminals 15 connected to bus bar 8 by bolt 18 andthe opposite terminal 16 connected to bus bar 10 by bolt 19. The terminals 20 of the same switches are connected to fuse contacts 25 by wire 28 ormay be connected directly by bolts, if desired, while the opposite terminals 21 are connected to fuse contacts l27 by wire 29, or otherwise.

Said switches are of well-known construction and operation, having contact making and breaking` blades operable by the usual push buttons a, Z), respectively.

`Similar switches l), E, F, are mounted between the bases 2, 3, in a like manner, connecting bus bars 9 and 10, as shown, each having one of its terminals 15 connected to bus bar 9 by bolts 18 and its other terminal 16 connected to bus bar 10 by bolt 19.

The other terminals 20 of said switch are connected to the fuse contacts 26 by wire 28, and the opposite terminals 21 of the same switches are connected to fuse contacts 27 by wire 29. Guter fuse contacts 30, 3l and 32 are spaced beyond fuse contacts 25, 2G and and are each provided with a suitabh-i branch circuit terminal binds ing post 3?. Between fuse contacts 25--80, 2(3-31, and 27--32 are inserted the usual fuses 36. Said fuse contacts and their fuses are mounted on the opposite outer sides of bases 23, as shown, the wiring being indicated in the diagram Fig. 3.

Referring to such diagram, numerals a0, ll1 and t2 represent the feeders connected to the bus bars 8, 9 and 10 by bolts 45, 46, ll?, or in any other suitable manner. ln said diagram l show one switch wired to a lamp circuit which will be suilicient to give an understanding of the circuit wiring and connections.

Assuming the bus bars to be energized by the feeders 40, 41, 112, from a suitable source, the circuit will be from plus or minus bus bar 10 through bolt 19 of switch F to terminal 16, blade 5() to terminal 20, to wire 28', to fuse clip 26, fuse 36 to clip 31, to branch terminal binding p etV 33, by wire 57, through lamps 56 and wire 55 to binding post 33 to fuse clip 32, fuse 36, fuse clip 27, to wire 29 to switch terminal 21, through blade 51, to terminal 15 and bolt 18 to bus bar 9. Similar connections through the other switches, bus bars and fuses to a lamp circuit will be readily understood without further description.

The construction and operation of the in vention will be readily understood from the foregoing description. The switches intervening between the bases 2, 3, are preferably covered by a. suitable face plate lA for each switch, whereby the switches and the fuses are concealed.

lt will be understood, of course, that any suitable type or construction. of switch other than the push button type may be substitutcd therefor and used with equally good results.

The bases, being mounted face-wise with relation to each other, provide ample space for location of the several parts Very economically, and admit of the wiring connections being easily made with readiness of access throughout.

It will be understood that the construction may be greatly Varied, changed or modified in size or other details by the skilled electrician, but. that all such changes are to be considered as within the scope of the following claims.
